双偏置蝶阀和三偏置蝶阀
2019年7月29日
蝶阀是最常用的阀门之一,我们通常具有同心软密封蝶阀,双偏心蝶阀和三重偏心蝶阀。通常,同心软密封蝶阀主要用于常温,低压工作条件,如供水和排水,水利工程,市政建筑等领域。该行是什么是双偏心蝶阀?什么是三重偏心蝶阀?他们适用于什么条件?双偏心蝶阀PTFE坐垫双偏心蝶阀是耐腐蚀性的。金属坐垫双偏心蝶阀是耐高温性的。但金属坐的双偏心蝶阀无法承受高压。当板与密封面直接接触时,在高压工作条件下使用时会导致泄漏。双偏心蝶阀用于供水和排水,污水,建筑,石油,化工,轻纺织,造纸,水电,冶金,能源等领域。三重偏心蝶阀三重偏心蝶阀是同心和双偏心蝴蝶阀的最佳态度。对于三重偏心蝶阀的座椅材料有更多的选择,并且能够适应低温和高温和各种酸, alkali and other corrosive media. In addition, triple eccentric butterfly valve can achieve zero leakage, especially suitable for large diameter valve, and, in the use of shut-off valve, can replace the gate valve and ball valve. When used to regulate the flow rate, it can replace the cumbersome globe valve. At present, the triple eccentric butterfly valve is widely used in oil mining, oil refining, petrochemical, energy generation and other important industrial fields of the pipelines. With people's continuous research,it is believed that the triple eccentric butterfly valve will be used in more and more fields.
